What Smithtown is specifically like to work in

Smithtown is our home base. We have built more pools in Smithtown and the surrounding hamlets than anywhere else on Long Island, and the town building department knows us by name. Most Smithtown permits are issued in three to four weeks, which is among the fastest on the Island. Soil conditions in Smithtown are generally favorable for both gunite and vinyl liner pools.

Services in Smithtown

Pool services we offer in Smithtown.

The full lifecycle of an inground pool, all handled by the same Legacy crew.

Custom gunite pool construction

A gunite pool is the right choice for most Smithtown homes that plan to stay in the family for more than a decade. The shell is sprayed concrete reinforced with steel and can hold any shape you can sketch — tanning shelves, sun ledges, vanishing edges, integrated spas, custom tile lines. The shell will last fifty years or more if it is built correctly.

Vinyl liner pool construction

A vinyl liner pool is a faster, lower-cost option that still gives you a real custom inground pool. The frame is steel or polymer panels, the floor is a vermiculite or grout mix, and the entire inside is wrapped in a printed vinyl liner. The trade-off is that the liner needs to be replaced every eight to twelve years.

Pool renovation and resurfacing

About half of our work in Smithtown is on pools we did not originally build. Renovation typically means new tile, new coping, new plaster (or polished aggregate or pebble finish), updated plumbing, and modern equipment. We can take a pool down to bare concrete and bring it back looking new.

Vinyl liner replacement

If your Smithtown pool is a vinyl liner pool and the liner is faded, wrinkled, leaking, or torn, it is time for a replacement. A standard liner replacement takes about a week. Most replacements include new gaskets, new face plates, and an inspection of the pool plumbing.

Weekly pool maintenance

Our weekly maintenance crew runs a route through Smithtown from May through October. Every visit includes water testing, chemistry adjustment, vacuuming, brushing, skimmer and pump basket cleanup, equipment check, and a short written report.

Hardscape and outdoor living

Most Smithtown projects include hardscape and outdoor living as part of the build — paver patios, retaining walls, outdoor kitchens, fire pits, pergolas, and lighting. Doing the hardscape with the pool means the lines flow together.

★★★★★

Same crew that designed our pool was the same crew that shot the gunite, set the tile, and started it up. Three years in, the plaster is still perfect and we still call the same number when we need anything. That is how a pool company is supposed to work.

Common Questions

Frequently asked questions about pools in Smithtown.

How long does it take to build a pool in Smithtown?

From signed contract to swimming, plan on about fourteen to twenty weeks for a gunite pool and eight to ten weeks for a vinyl liner pool in Smithtown. The biggest variable is the permit timeline — the Smithtown Town Building Department typically takes 3 to 6 weeks to issue. We build the permit timeline into the schedule we hand you at contract.

What is a fair price for a custom pool in Smithtown?

Most full Smithtown projects come in around $100,000 to $300,000. That includes the pool itself, excavation, plumbing, equipment, coping, deck or patio, and the fence the state requires. The big swings are size, finish material, and how much hardscape is in the package.

Do I need a permit to build a pool in Smithtown?

Yes. Every inground pool in Smithtown requires a permit from the Smithtown Town Building Department. We handle the permit application, the drawings, the engineering when required, and the inspections as part of every build. New York State also requires a permanent fence around every inground pool with a self-closing, self-latching gate.

Can you build a pool on a difficult Smithtown lot?

Most of the time, yes. We have built on sloped lots, lots with bedrock at shallow depth, lots with no rear access where we had to crane equipment in, and lots where the pool location had to be chosen to save specimen trees. We will give you a straight answer during the site visit about whether your specific lot is buildable and what the cost implications are.

Do you service pools in Smithtown that were built by other companies?

Yes. Most of our weekly maintenance route in Smithtown is on pools built by other contractors. We do not require you to have been an original construction client to take on your maintenance, opening, closing, repair, or renovation work.

What makes building a pool in Smithtown different from other Long Island towns?

Smithtown is our home base. We have built more pools in Smithtown and the surrounding hamlets than anywhere else on Long Island, and the town building department knows us by name. Most Smithtown permits are issued in three to four weeks, which is among the fastest on the Island. Soil conditions in Smithtown are generally favorable for both gunite and vinyl liner pools. That is one of the reasons it pays to hire a builder who knows Smithtown specifically, not just a general Long Island pool company.
